Most quadratic functions(which is what you have there, to a degree of 2) are solved using factoring and the zero product law. If you can not factor then you have to use the quadratic formula or graph it. However this one can be factored.
It's pretty simple to just factor it by inspection but I use the chart method, if you know decomposition that works as well.
Factoring gives us,

Then you set each factor to 0 and solve for x,



And the second one,


The solutions to this equation are
x = -1/2, 3
Answer:
The correct answer is C
Step-by-step explanation:
Please give thanks and brainlist
Answer:
the answer is B because it has only one unknown and also it is a linear equation so it will have only one answer which is (2 )
The answer will be a because they are similar and by law the ratio can be cubed to find ratio of volume
